Noah's Ark- Part 3

Cain and Abel represent the conflicts in us between the innate purity of the psyche (Abel) and the ever dissatisfied desires we have (Cain).  Our desires "kill" the purity of the psyche (Cain kills Abel).  Abel, that part of us, does not cease to exist, by "dying" is represented how it has become almost completely powerless, trapped, overwhelmed, by the spread of desire.  When desire rules us psychologically, Abel is rendered "dead".
